Description

Detailed Description of the Invention

[0001]

[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing braking device which is provided in, for example, an opening / closing mechanism for a door or a lid, and which suppresses a sudden movement of a moving member which is a constituent member of the opening / closing mechanism. .

[0002]

BACKGROUND OF THE INVENTION Opening and closing mechanisms for furniture such as doors and windows and furniture,
As an opening / closing mechanism for various doors of Buddhist altars, safes, automobiles, etc., or as an opening / closing mechanism for Western style toilet bowl lids, piano lids, etc., most basically, a rotating hinge is provided between the base material and the opening / closing member, A configuration is adopted in which the both are rotatably connected by this rotating hinge. If these doors, lids, etc. have a large weight, or if these doors, lids, etc. are inferior in strength due to their material or structure, they may be damaged by sudden opening / closing operations. Etc.,
A shock absorbing braking device may be used for the purpose of suppressing a sudden movement of the opening / closing member.

Many of such braking devices are provided so as to connect the base material and the opening / closing member at a position separated from the rotary hinge serving as a rotary fulcrum in the radial direction. The existence of the braking system can be clearly confirmed from the outside, and this type of braking system is structurally
Since it is relatively large, it has been a factor of impairing the appearance of doors and lids, which are opening / closing members.

Most of the shock absorbing means in such a braking device uses a viscous fluid such as air, oil or grease, and a seal mechanism for preventing the outflow of the air or the viscous fluid is separately required. Or, as mentioned above, the braking device inevitably becomes large in structure,
The increase in weight led to an increase in manufacturing cost. In addition, these air and viscous fluids can always obtain only a constant braking force regardless of the magnitude of the load, abrupt load change, or the direction of the load, and are not necessarily the optimum shock absorbing means applied to the opening / closing mechanism. I couldn't say.

On the other hand, when the load changes slowly (when the load resistance is applied slowly and gradually), it deforms extremely flexibly and when the load changes rapidly (when the load resistance is applied at once at once). In particular, bouncing putty is known as a material having a strong drag force and a property of maintaining its original shape.

However, this bouncing putty has a weak self-shape-retaining property and flows due to gravity even when there is no load, so that it is difficult to maintain a specific shape, its own weight is heavy, and it is relatively expensive. There are limited applications that have been used while having the above excellent characteristics,
For example, toys for children and research materials for measuring rheology,
Alternatively, Japanese Patent Application Laid-Open No. 4-117903 related to the applicant's application
It was used in very few fields, such as the issue "Stress buffering structure in shoes".

[0007]

[Technical Items Attempted to Develop] The present invention was devised in view of such a background, and paying attention to the characteristics of the bouncing putty, the bouncing putty is opened and closed by a mechanism such as a door or a lid. This is an attempt to develop a new braking device that can be applied to a desired shock absorbing force with an extremely simple structure and can cope with various changes in load.

[0008]

Configuration of the Invention

[Means for Achieving the Object] That is, the braking device according to the first aspect is provided for an opening and closing mechanism such as a door and a lid, and is for absorbing shock for suppressing abrupt movement of a moving member which is a constituent member of the opening and closing mechanism and the like. In the device, the shock absorbing device uses a bouncing putty as a shock absorbing means,
An adhesive strengthening means is provided between the bouncing putty and its installation site.

In addition to the above requirements, the braking device according to a second aspect is characterized in that the bouncing putty is arranged so as to receive a force in the shearing direction.

Further, in addition to the requirements of claim 2, the braking device according to claim 3 is arranged by filling the bouncing putty between the components of the rotary hinges that are assembled in a multiple concentric manner. It is characterized by that.

Further, in addition to the above requirements, the braking device according to claim 4 is a machine in which the adhesion strengthening means is a chemical adhesion strengthening means using a primer, an adhesive, or the like, and unevenness is provided at an installation site of the bouncing putty. It is characterized in that it is configured by including both or one of them.

Further, in addition to the above-mentioned requirements, the braking device according to a fifth aspect is characterized in that the shock absorbing means is constituted by combining a bouncing putty and another elastic member.

Further, in addition to the above requirements, the braking device according to claim 6 is provided with a one-way movable mechanism for restricting the braking direction in the shock absorbing device or other portion of the opening / closing mechanism or the like. It is a feature.

Further, in addition to the above requirements, the braking device according to a seventh aspect is characterized in that the bouncing putty contains elastic micro hollow spheres. Then, the object of the invention is to be achieved by using the constitution of the invention described in each of these claims.

[0015]

That is, in the braking device according to the first aspect of the present invention, the bouncing putty is used as the shock absorbing means provided in the opening / closing mechanism and the adhesion strengthening means is provided between the bouncing putty and the installation site thereof. It takes the structure of. As a result, the characteristics of the bouncing putty are fully utilized, and when the door, lid, etc. are opened and closed slowly, the braking force is low and it is possible to open and close without receiving much resistance. When the lid or the like is suddenly opened / closed, a high braking force is applied, so that the doors or lids, which are opening / closing members (moving members), do not violently collide with the base material, which is the supporting member.

The braking device according to a second aspect of the invention has a structure in which the bouncing putty is arranged so that a force is applied in the shearing direction. As a result, the impact of the bouncing putty does not depend on the direction of the load, even for the force in the shearing direction, which could not be dealt with by air or viscous fluid, which has a high shock absorbing force only for the force in the compression direction. It becomes possible to obtain absorption power.

Furthermore, a braking device according to a third aspect of the present invention has a structure in which bouncing putties are filled and arranged between the constituent members of a rotary hinge that are combined in a multiple concentric manner. Accordingly, the bouncing putty as the shock absorbing means does not appear outside the opening / closing member, and the appearance of the opening / closing member is not damaged. In addition, the effect of suppressing the shearing force due to the twist generated by the rotation can be obtained.

Furthermore, the braking device according to a fourth aspect of the present invention is configured such that the adhesion strengthening means comprises both chemical adhesion strengthening means and mechanical adhesion strengthening means, or either one of them. As a result, the bonding between the bouncing putty and its installation site becomes stronger, and the characteristics of the bouncing putty are fully exhibited.

Further, in the braking device according to the fifth aspect, the shock absorbing means is constituted by combining the bouncing putty and another elastic member. As a result, it becomes possible to further improve the shock absorbing power and to supplement the disadvantage of the bouncing putty, which is inferior in self-shape retention.

Furthermore, the braking device according to the sixth aspect has a structure in which a one-way movable mechanism for restricting the braking direction is provided in the shock absorbing device in the opening / closing mechanism or the like or in another portion. As a result, if a particularly high braking force is desired when the lid is closed, such as a Western-style toilet bowl lid or piano lid, the one-way movable mechanism should be arranged so that the shock absorbing means operates only when the lid is closed. Well, if this is done, the lid of the toilet bowl or the lid of the piano can be opened without receiving much or any resistance when the lid is opened, while a high braking force acts when the lid is closed. And the lid of the piano does not close hard.

Furthermore, the braking device according to a seventh aspect of the invention has a structure in which the bouncing putty contains elastic micro hollow spheres. As a result, the bouncing putty having the above characteristics is further provided with the self-shape retaining property, and the degree of freedom in the arrangement of the bouncing putty is further improved.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The braking device of the present invention will be specifically described below with reference to the drawings. The braking device of the present invention is for braking when closing a toilet seat and lid of a Western-style flush toilet, braking doors, doors, and other fittings, or braking sashes, window frames, and the like not included in these fittings categories ( For example, dampers for horizontal sliding windows in smoke exhaust systems of buildings), braking of lids of pianos and furniture,
In addition, it is widely used as a substitute for dampers, shock absorbers, cylinders, etc. attached to various rotating parts, rotating parts, and sliding parts.

In the following description, the opening / closing member 3 is provided between the base member 2 which is a supporting member and the opening / closing member 3 (corresponding to the moving member in the claims). A description will be given of a braking device 1 applied to the turning hinge 4 as an application target, with a turning hinge 4 rotatably connected to the base material 2 as an example. First, the braking device 1 of the present invention is characterized in that a bouncing putty P is used as the shock absorbing means 10. Therefore, the braking device 1 of the present invention
Further, prior to the description of the rotary hinge 4 including this, the bouncing putty P will be first described.

The bouncing putty according to the present invention
Nincing putty) P is a general term for deformable putty substances that deform extremely flexibly under a slow load change, but show a strong resistance to a sudden load change and have high elasticity or rigidity. And includes, for example, those disclosed in US Pat. No. 2,541,851.

The structure of this product is composed of a network of silicone having hydrophobic methyl groups and the like, most of which are crosslinked, and a system composed of a viscous liquid reactive product of a boron mixture and methylsilicone. It has a two-layer structure. The hydrophilic reaction product then forms a layer in the interstices of the crosslinked silicone. It is also considered that the unique property of this product is that the hydrophilic and hydrophobic groups are in an equilibrium state, and in addition, the friction between these two groups is large.

That is, when this substance is dropped onto a relatively hard surface, for example, a large frictional force acts between the hydrophilic group and the hydrophobic group, and as a result, each molecule does not slip, resulting in elasticity. It exhibits a solid-like property with properties, and exhibits a kind of rigidity close to a kind under a sharp impact such as hitting with a hammer. On the other hand, when the pressure is gradually applied, the boron component can flow out between the meshes of the network by overcoming the frictional force, so that the boron component is extremely flexibly deformed.

An example of the components of the bouncing putty P is as follows. Boron-containing siloxane 50 to 80% Pigment + Silicon dioxide 10 to 30% Diorganopolysiloxane 0 to 15% Higher fatty acid and other 1% Also, bouncing putty is obtained by treating organopolysiloxane with a mixture of boron and heat. It is continuously obtained by appropriately providing either one or both of the catalysts. Where the mixture of boron is pyroboric acid,
Specific boron mixtures can be selected depending on the properties desired for the product, including boric anhydride, boric acid, ethyl borate, other borate esters, and the like.

An example of the method for producing the bouncing putty P will be shown below. The organopolysiloxane used in the manufacturing process is
It is an oily methyl siloxane, which is obtained by hydrolysis of almost pure dimethyl silicone halogen compound, and its structure is represented by (CH ₃ ) ₃ SiO _0.5 at the ends and (CH ₃ ) ₂ SiO at the middle part. It is what is done.

First, 75 parts of dimethyl silicone oil (representing parts by weight; the same applies hereinafter) and 10 parts of pyroboric acid are mixed, and this mixture is heated in an oven at 150 ° C. for 2 hours. At the end of the heating the mixture becomes a somewhat elastic gel. To 45 parts of this gel, 90 parts of lithopone (white pigment) and 0.9 parts of benzoyl peroxide are mixed until they become a solid, and further 45
Dimethyl silicone oil and 0.9 parts of benzoyl peroxide are added to further solidify.

The solidified product is heated in an oven at 100 ° C to 150 ° C for 2 hours. By kneading the finished product with the fingers of the hand, it becomes putty and has high adhesiveness and resilience. It should be noted that the use of a hydrolyzable alkyl borate or the same amount of catalyst is convenient for dispersing the boron mixture in methyl silicone oil.

By changing the amount of the boron mixture, the amount of catalyst, the heating time, etc., the component ratio of hydrophilicity and hydrophobicity changes, and as a result, the elasticity of the bouncing putty P as a shock absorbing means is changed. And flexibility. The elasticity and flexibility can also be adjusted by adding a hydrophilic or hydrophobic substance such as glycerin or oleic acid.

The bouncing putty P can be used alone as a matter of course, but so-called filler as described below can be added to the bouncing putty P. Such a filler has an appropriate bulk, and if it can be integrated with the bouncing putty P (dispersed in the bouncing putty P and still not separated), it may have a suitable shape such as a flake shape even if it is solid or not elastic. However, elastic micro hollow spheres as described below are preferable. Next, the elastic micro hollow spheres that can be contained in the bouncing putty P will be described. The elastic micro hollow spheres referred to here are powders represented by, for example, Expancel (registered trademark) developed by Expancel, Sweden, and Matsumoto Microspheres (registered trademark) manufactured by Matsumoto Yushi-Seiyaku Co., Ltd. is there. EXPANCEL is an organic micro hollow sphere made of a copolymer of vinylidene chloride and acrylonitrile manufactured in 1980, which contains isobutane as an expanding material and is encapsulated.

There are unexpanded (unfoamed) and expanded (expanded) expansels. The expanded particles have an average particle size of 40 μm and a particle size range of 10 to 100 μm.
m is larger than that of unexpanded particles having an average particle size of 10 μm and a particle size range of 5 to 30 μm, and expanded particles have excellent buffering properties.

The Expancel has a shell wall of 0.1 μm.
Since it is elastic to some extent, it is compressed when a load is applied,
Since it has the property of returning to the original when the load is stopped,
When this is mixed in the bouncing putty P, the shock resistance and the cushioning property are enhanced. Since Expancel is a sphere, it has a much better stress distribution than other fillers.

The Matsumoto microspheres are roughly classified into those containing a low boiling point hydrocarbon with a vinylidene chloride copolymer as a shell wall and those containing a low boiling point hydrocarbon with a shell wall not containing vinylidene chloride. Among them, the expanded (foamed) F-80 having a particle size range of 20 to 80 μm
ED is preferred.

Although these elastic micro hollow spheres depend on the adjustment of the bouncing putty P, 1 to 10 parts of the bouncing putty P is usually added and mixed with respect to 100 parts by weight. In addition, the elastic micro hollow sphere is used for bouncing putty P.
To mix in, use a kneader or the like. By the way, as described above, the bouncing putty P has a weak self-shape retention property as a single substance and flows if left unattended, but by incorporating elastic micro hollow spheres into the bouncing putty P, the bouncing putty P may have a self-shape retention property. become. Further, the bouncing putty P itself has a relatively large specific gravity, but by incorporating elastic micro hollow spheres having a small specific gravity, the overall weight can be set small.

The braking device 1 of the present invention using the bouncing putty P as the shock absorbing means 10 and the rotary hinge 4 to which the braking device 1 is applied will be described below. First, only the bouncing putty P shown in FIGS. 1 to 3 or the one containing elastic micro hollow spheres therein is used for the shock absorbing means 1.
A basic embodiment in which 0 is configured will be described. In this embodiment, a turning piece 42 is formed on one end of which the turning hinge 4 is formed, and a turning piece 42 is fitted on the turning piece 42. The rotating casing 43 formed and the end portion of the rotating casing 43 where the locking projection 41 is not formed are engaged, screwed,
It is configured by a fixed cap 44 that is fixed by fitting (tight fitting) or adhesion or welding. Moreover, brass is used as a material for each of the constituent members of the rotary hinge 4.
Metals such as stainless steel and aluminum, or various industrial plastics having high mechanical strength, other synthetic resins, synthetic rubbers, etc. can be used. Further, when the airtightness of the connecting portion between the rotating casing 43 and the fixed cap 44 is insufficient and the bouncing putty P to be filled may flow out, a simple sealing mechanism such as an O-ring is attached. Is also possible.

The fixed cap 44 is provided with a projection receiving port 45 for allowing the locking projection 41 of the rotary piece 42 to project, and a sliding contact surface of the rotary piece 42 with the rotary casing 43. Is partially recessed, and a filling space S of the bouncing putty P, which is a characteristic configuration of the present invention, is formed. Then, the filling space S is filled with the bouncing putty P, and is firmly adhered to the sliding contact surfaces of the rotary piece 42 and the rotary casing 43, which are the installation sites thereof, and if fixed, the braking device 1 of the present invention is obtained. A pivoting hinge 4 is provided which comprises.

The "strong adhesion" described here means the adhesion strengthening means described in claim 1, and as an example thereof, a chemical adhesion strengthening means such as a primer or an adhesive can be adopted. In this adhesion strengthening means, the bouncing putty P rotates without being restricted by the rotating piece 42 and the rotating casing 43.
This is a measure taken to prevent a situation in which the original action cannot be exerted. For this purpose, for example, the above-mentioned chemical adhesion strengthening means is adopted. For example, metal and silicone (bouncing putty P), hard resin such as polycarbonate and silicone (bouncing putty) are used in relation to the material of the rotating piece 42 or the rotating casing 43. It is desirable to fill the bouncing putty P after applying a primer and an adhesive suitable for each joining such as P). Specifically, Toray Dow Corning Silicone Co., Ltd.'s primers A to D, Toshiba Silicone Co., Ltd.'s FC10α,
β, etc. can be used.

The filling space S is formed by recessing a part of the sliding contact surface on the outer periphery of the rotating piece 42 as described above, and by recessing a part of the inner peripheral surface of the rotating casing 43. It is also possible to form the filling space S, and it is also possible to form the filling space S by recessing both the rotating piece 42 and the rotating casing 43. Further, when the sliding contact surfaces of the rotating piece 42 and the rotating casing 43 are recessed, the surface roughness of the recessed surface is formed to be rough, or grooves or creases are formed in the axial direction so that the bouncing putty P is installed at an uneven surface. It is desirable to also use a mechanical adhesion strengthening means such as provision of. Incidentally, when the groove or the fold is formed in the axial direction, the bouncing putty P enters the groove or the fold, and this serves as a resistance when the rotating piece 42 and the rotating casing 43 rotate, and the bouncing putty P is formed. This effectively prevents the slip. That is, it acts so as to complement the strengthening of the adhesion between the two.

Further, it is possible to use only one rotating hinge 4 thus constructed, but it is also possible to use a plurality of connecting hinges. In that case, for example, as shown in FIGS. 4 (a) and 4 (b), instead of the locking projection 41, a locking recess 46 that engages with the locking projection 41 is provided with a rotation piece 42 and a rotation top. The rotating hinge 4 formed on either or both of the moving casing 43 is used. Incidentally, when the connection mode shown in FIG. 4A is taken, the rotary casing 43 of the right rotary hinge 4 is fixed to the base material 2 (or the opening / closing member 3) and the right rotary hinge 4 is rotated. Moving piece 4
2 and the rotary casing 43 of the left rotary hinge 4 are fixed to the opening / closing member 3 (or the base material 2). Further, when the connection mode shown in FIG. 4B is adopted, the central rotating hinge 4 is fixed to the base material 2 (or the opening / closing member 3), and the rotating casing 43 and the right side of the rotating hinge 4 on the left side are fixed. The rotating piece 42 of the rotating hinge 4 is fixed to the opening / closing member 3 (or the base material 2).

As shown in FIG. 1, such a rotating hinge 4 is provided with a base material 2 which is a supporting member (which corresponds to the piano main body if the application object is a piano) and an opening / closing member 3 (the application object is a piano). (If it corresponds to the lid of the piano, if any), and when both are rotatably connected, the rotating piece 42 and the rotating casing 4 can be opened by slowly opening and closing the opening / closing member 3.
The bouncing putty P is freely deformed in response to the change in the relative position with respect to the opening / closing member 3. On the other hand, the opening / closing member 3 tries to move suddenly like when the opening / closing member 3 in the opened state is accidentally released. In this case, the bouncing putty P tries to keep its original shape against this.

Therefore, when the opening / closing member 3 is opened / closed by a normal operation, it can be opened / closed without much resistance, and as described above, the hand is accidentally released from the opened / closed member 3. In the unlikely event that you did,
Two contradictory actions, namely, abrupt fall of the opening / closing member 3 are prevented.

Next, another embodiment in which the arrangement of the braking device 1 of the present invention having such excellent characteristics is different will be described. That is, in the embodiment shown in FIGS. 1 to 3, the bouncing putty P is arranged so that a force is applied from the shearing direction, whereas in the embodiment shown in FIG.
The bouncing putty P is arranged so that force is applied from both the compression (pulling) direction and the shearing direction. The embodiment shown in FIG. 5 will be described below.

The structure of the rotary hinge 4 is substantially the same as the structure of the rotary hinge 4 shown in FIGS. However, the formation location of the filling space S where the bouncing putty P is provided is different, and as shown in FIG. 5A, the end of the rotating piece 42 on the side where the locking projection 41 is not formed is approximately half over a certain depth. A concave shape is formed in a circular shape or a fan shape, and the filling space S is formed therein. Therefore, the bouncing putty P filled in the filling space S is mainly subjected to the stress in the shearing direction around the outer peripheral surface bonded to the rotary casing 43 or the fixed cap 44, and the bonding surface to the rotary piece 42 is bonded. From the above, the stress in the compression direction or the tensile direction acts on almost the entire turning piece 42.

In the embodiment shown in FIG. 5 (a), it is possible to additionally provide the filling space S at the location provided in the embodiment shown in FIGS. In that case, it is possible to fill the bouncing putty P from the filling space S provided on the outer periphery of the rotating piece 42, for example, by making the filling spaces S of both communicate with each other. Incidentally, the shape of the bouncing putty P when such a filling form is taken is shown in FIG.
As shown in (b).

Further, it is also possible to adopt an arrangement mode as described below. That is, as shown in FIG.
3 is composed of a rectangular tubular member having a square cross section, for example, and on the other hand, a pawl portion 42a is provided in four directions on the outer periphery of the rotary piece 42 fitted in the rotary casing 43. An arrangement in which four bouncing putties P formed in a rod shape are inserted between the claw portions 42a of the rotating piece 42 and the four corners of the inner surface of the rotating casing 43 in the filling space S formed between Aspects are also possible. Incidentally, in the case of adopting such a configuration, the bouncing putty P cannot be used as it is, and the bouncing putty P is used by filling an elastic tube or the like having both ends sealed, for example.

When this arrangement is adopted, the bouncing putty P is mainly stressed in the compression direction. The claws 42a may be provided on the side of the rotating casing 43, and instead of the claws 42a, a concave portion that engages with the rod-shaped bouncing putty P may be formed in the rotating piece 42 or the rotating casing 43. Of course, it is possible to do so. Further, in the embodiment shown in FIG. 6, the bouncing putty P formed into a rod shape is used, but it is also possible to arrange the bouncing putty P so as to fill the entire filling space S. By the way, when such an arrangement is adopted, the tube or the like is not necessary.

Next, an embodiment in which the shock absorbing means 10 is constructed by combining the bouncing putty P and another elastic member E will be described. That is, FIG. 7 shows an embodiment in which the rotary hinge 4 itself is made of urethane rubber which is another elastic member E, and the bouncing putty P having a constant thickness is formed on the outer peripheral surface of the other elastic member E. A layer is formed. The urethane rubber used here is a representative example of rubber or elastomer, and various materials can be used as long as it is a relatively firm elastic body having a small permanent set in addition to silicone rubber.

When the rotary hinge 4 itself is made of urethane rubber or the like as described above, the rotary hinge 4 is twisted as the opening / closing member 3 is rotated, and the rotary hinge 4 is twisted with this twist. Tries to shrink somewhat in the axial direction. Therefore, the embodiment shown in FIG. 8 utilizes this property for braking the opening / closing member 3. That is, in the embodiment shown in FIG.
The turning hinge 4 formed of urethane rubber or the like is formed in a stepped shape with the diameter of both ends thereof being slightly larger than the diameter of the intermediate portion thereof, and an inner flange-shaped rib is formed on the inner peripheral surface so as to cover the outside thereof. A protective cover 48 having 47 is provided. Incidentally, in the case of adopting such a configuration, the step portion 4a at both ends of the rotary hinge 4 rubs against the rib 47 of the protective cover 48 due to the axial contraction caused by the twist of the rotary hinge 4. However, the frictional force generated thereby can be utilized for braking together with the bouncing putty P arranged on the outer periphery of the other elastic member E.

Further, in the embodiment shown in FIG. 9, a leaf spring is adopted as another elastic member E. A bouncing putty P is adhered between a plurality of rectangular plate-shaped leaf springs, and both ends thereof are further attached. The holding block 49 is used for fixing. As the fixing means of the holding block 49, various fixing means such as fixing with a screw as shown in the drawing or fixing with an adhesive can be adopted. Further, as shown in FIG. 10, it is possible to adopt a configuration in which the rotating piece 42 and the rotating casing 43 are provided in an eccentric state, and the bouncing putty P is filled and arranged in the filling space S formed in the gap. is there.

Further, as claimed in claim 5, the braking device 1 of the present invention or the rotating hinge 4 provided with the braking device 1 or between the base member 2 and the opening / closing member 3, or a connecting portion thereof is provided with a braking direction. It is also possible to provide a one-way movable mechanism 20 that regulates the above. First, the one-way movable mechanism 20 shown in FIG. 11A will be described. This is an example of applying a so-called ratchet mechanism,
As an example, the rotating piece 42 is composed of two members, and the engaging claws 51 as shown in the drawing are formed at the connecting portions of these two members,
Further, a biasing means 52 is provided so that these two members bias in the approaching direction.

Incidentally, such a one-way movable mechanism 20
In the case of adopting, the shape of the engaging claw 51 is formed such that a steep slope portion and a steep slope portion are continuous, and the engaging pawl 51 is rotated in a direction in which the steep slope portions come into contact with each other. When the top 42 or the rotary casing 43 is rotated, the engaging claws 51 are firmly engaged with each other to rotate integrally, so that a large braking force is obtained. When the turning piece 42 or the turning casing 43 is turned in the contacting direction, the engaging claw 51 slides and only one of the turning piece 42 or the turning casing 43 turns, and the braking force is almost zero. Does not work

It is also possible to apply a one-way movable mechanism 20 as shown in FIG. 11 (b). This is an embodiment in which a coil spring 53 that contracts or expands in the radial direction depending on the rotation direction is applied. In other words, the turning piece 42 is taken as an example, and two members as shown in the figure are connected by the coil spring 53. In this embodiment, the bouncing putty P is arranged in the same manner as the embodiment shown in FIG. 5, but the turning piece 42 is of course the same as the embodiment shown in FIGS.
It is also possible to fill the bouncing putty P in the cylindrical space between the rotary casing 43 and the rotary casing 43.

By the way, when the one-way movable mechanism 20 having such a structure is applied, when the rotating piece 42 or the rotating casing 43 is rotated in the direction in which the coil spring 53 contracts in the radial direction, The coil spring 53 acts so as to tighten the connection portion of the two members from the outside, so that the two members are integrally rotated. Therefore, the bouncing putty P is activated and a large braking force is obtained. On the other hand, when the rotating member 42 or the rotating casing 43 is rotated in the direction in which the coil spring 53 expands in the radial direction, the two members rotate without being restricted by each other, and the coil is almost coiled. The braking is performed only by the elastic force of the spring 53.

Further, the embodiment shown in FIG. 12 is not an embodiment to which the one-way movable mechanism 20 is applied, but the embodiment shown in FIG.
Similar to the embodiment shown in (b), this embodiment uses the coil spring 53, and therefore will also be described here.
That is, in the embodiment shown in FIG. 11B, the one-way movable mechanism 20 is configured by utilizing the property that the coil spring 53 contracts or expands in the radial direction depending on the twisting direction, whereas the coil spring 53 is configured. Is simply used as another elastic member E.

In the embodiment shown in FIG. 12,
The rotary hinge 42 existing in the embodiments shown in FIGS. 1 to 3 is discharged, and the rotary hinge 4 is constructed with the rotary casing 43 and the rotary cap 54 having a structure similar to the fixed cap 44 as a basic member. Are configured. That is, the rotary casing 43 having the locking projection 41 formed at one end and the rotary cap 54 having the locking projection 41 also formed at the one end are fitted in an idle state, and both of them are fitted together. The connection is made by the coil spring 53, the outer peripheral portion of the rotating casing 43 is formed as a recess, and this is used as a filling space S, and the bouncing putty P is filled therein.

Further, in the embodiment shown in FIG. 13, the one-way movable mechanism 20 is arranged by utilizing the filling space S of the bouncing putty P constituting the braking device 1 of the present invention. That is, FIG. 13 shows that the filling space S of the bouncing putty P is formed between the rotating casing 43 and the rotating piece 42, and the inner peripheral surface of the rotating casing 43 or the outer peripheral surface of the rotating piece 42 is formed. It is formed so that the interval between and gradually changes depending on the change in the relative position between the two.

If the bouncing putty P is arranged in a part of the filling space S as shown in the figure, the rotating piece 42 is rotated counterclockwise with the state shown in FIG. 13 as the initial state. 42 is in an unloaded state until it abuts on the bouncing putty P (approximately 90 ° in the illustrated embodiment). On the other hand, if the rotating piece 42 is rotated clockwise from the initial state shown in FIG. Immediately, the rotating piece 42 comes into contact with the bouncing putty P, and the desired braking action is obtained. In the embodiment shown in FIG. 13, the bouncing putty P alone cannot maintain the shape and flows. Therefore, in practice, a flexible casing member having the shape is prepared, and the bouncing putty P is placed therein.
It is necessary to take a method such as filling the same or forming a sponge into the shape and impregnating this with the bouncing putty P.

Furthermore, it is also possible to employ a braking device 1 as shown in FIG. In the embodiment shown in FIG. 14, a rotation piece 42 has a locking portion 55 having a locking projection 41, and a rotation shaft 56 that is fitted to the locking portion 55 in a state where movement in the rotation direction is restricted.

A space defined by the portion 55 and the fixed cap 44 is a filling space S,
The bouncing putty P is filled in here.

Incidentally, in the case of such a construction, when the rotating shaft 56 is rotated clockwise with the state shown in FIG. 14B as the initial state, the spiral spring 57 is unwound and expanded in the expanding direction. To move. Therefore, the bouncing putty P is subjected to the shearing direction drag force caused by the rotation of the rotation shaft 56, as well as the compression and pulling direction drag force caused by the expansion of the spiral spring 57, and further the contraction direction drag force of the spiral spring 57. In addition, a complex braking action can be obtained. On the other hand, FIG.
When the rotating shaft 56 is rotated counterclockwise with the state of (b) as the initial state, the spiral spring 57 is wound tightly and moves in the contracting direction. Also in this case, the bouncing putty P is subjected to a shearing force and a compressing and pulling direction drag force, and in addition to this, a drag force in the expansion direction of the spiral spring 57 acts to obtain a composite braking action. Become.

The braking device 1 of the present invention is configured as described above, and the following effects are exhibited by having such a configuration. That is, in the braking device according to the first aspect, the bouncing putty P is used as the shock absorbing means 10 provided in the opening / closing mechanism or the like, and the adhesion strengthening means is provided between the bouncing putty P and the installation site thereof. Take the configuration. As a result, the characteristics of the bouncing putty P are fully utilized, and when the door, lid, etc. are slowly opened and closed, the braking force is low and it is possible to open and close without receiving much resistance. When the door, the lid, etc. are suddenly opened and closed, a high braking force is applied, so that the doors, lids, etc., which are the opening / closing members (moving members) 3, do not violently collide with the base material 2, which is their supporting member. .

The braking device according to a second aspect of the invention has a structure in which the bouncing putty P is arranged so that a force is applied in the shearing direction. As a result, the impact of the bouncing putty does not depend on the direction of the load, even for the force in the shearing direction, which could not be dealt with by air or viscous fluid, which has a high shock absorbing force only for the force in the compression direction. It becomes possible to obtain absorption power.

Furthermore, the braking device according to the third aspect of the invention has a structure in which the bouncing putty P is filled and arranged between the constituent members of the rotary hinge 4 combined in a multiple concentric manner. As a result, the bouncing putty P as the shock absorbing means 10 does not appear outside the opening / closing member 3, and the appearance of the opening / closing member 3 is not impaired. Further, the effect of suppressing the shearing force due to the twist generated by the rotation can be obtained.

Furthermore, the braking device according to a fourth aspect of the present invention is configured such that the adhesion strengthening means comprises both chemical adhesion strengthening means and mechanical adhesion strengthening means, or either one of them. As a result, the bonding between the bouncing putty P and its installation site becomes stronger, and the characteristics of the bouncing putty P are fully exhibited.

Further, in the braking device according to the fifth aspect, the shock absorbing means 10 is constructed by combining the bouncing putty P and another elastic member E. As a result, it becomes possible to further improve the shock absorbing power and to supplement the disadvantage of the bouncing putty P, which is inferior in self-shape retention.

Furthermore, the braking device according to claim 6 has a structure in which a one-way movable mechanism 20 for restricting the braking direction is provided in a device for absorbing shock in an opening / closing mechanism or the like or another portion. Accordingly, when it is desired to obtain a particularly high braking force when the lid is closed, such as a Western-style toilet bowl lid or a piano lid, the one-way movable mechanism 20 is arranged so that the shock absorbing means 10 operates only when the lid is closed. If you do this, you can open the lid of the toilet bowl and the lid of the piano without receiving much or any resistance when opening the lid,
On the other hand, when the lid is closed, a high braking force does not act and the lid of the toilet bowl and the lid of the piano do not close violently.

Furthermore, the braking device according to claim 7 has a structure in which the bouncing putty P contains elastic micro hollow spheres. As a result, the bouncing putty P having the above characteristics is further provided with self-shape retention, and the degree of freedom in the arrangement of the bouncing putty P is further improved. The synergistic effects produced by the configurations described in the claims are intended to expand the applications of the bouncing putty P, and to manufacture the bouncing putty P in a lightweight and small size with a simple structure and to absorb a desired shock. Thus, a very useful braking device 1 that can obtain a force and can cope with various load directions is provided.
